We look at the division of 252015 by 22 
We're looking to find how many times 22 goes into 252015.

Let's proceed to step 1:
22 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 22

Step 2:
If we divide 25 by 22, we get 1 and a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 22 from 25, we get 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 22

Step 3:
32 divided by 22 is 1 with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtract 22 from 32 to get 10.
Bring next digit (0) of the dividend behind the 10 and repeat the process: 100 / 22

Going ahead to step 4:
100 divided by 22 is 4 with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 114.0
Deduct 88 from 100 and we're left with 12.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 22

Advancing to step 5:
The number 22 fits into 121 5 times, leaving a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 1145.0
The remainder is 11 after subtracting 110 from 121.
Bring next digit (5) of the dividend behind the 11 and repeat the process: 115 / 22

Step 6:
If we divide 115 by 22, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 11455.0
Subtract 110 from 115 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
50 divided by 22 is 2 with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 11455.2
Subtract 44 from 50 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
If we divide 60 by 22, we get 2 and a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 11455.22
If we subtract 44 from 60, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 11455.22 with a remainder of 0.016.
